.SHORT TERM...VALID FOR TUE AND WED...
UPDATE FOR ZONES TONIGHT. NO UPDATE FOR WRKAFP. 250MB JET MOVING OVER THE
AREA AND IS CREATING A STRONG AREA OF DIVERGENCES ALOFT. THUNDERSTORMS
HAVE BEEN DEVELOPING IN THIS AREA OF LIFT THROUGH THE EVENING AND
EXPECTED THEM TO CONTINUE DEVELOPING THROUGH THE NIGHT. CONVECTION IS MOVING
EAST AND HAVE RAISED POPS TO HIGH SCATTERED OVER THE SOUTHEAST. WILL KEEP
CHANCE OF THUNDERSTORMS GOING TONIGHT OVER CENTRAL AND WESTERN ZONES AS IR
IMAGE SHOWING GOOD BAND OF CONVECTION CONTINUING OVER EASTERN IDAHO AND
WESTERN WYOMING. SEVERAL SHORT WAVES MOVING UP THE FRONT SIDE OF HIGH
PRESSURE RIDGE IS CAUSING THIS CONVECTION TO DEVELOP. CLOUDS AND TEMPERATURE
FORECAST LOOKS GOOD AND MADE NO ADJUSTMENTS. RICHMOND
.LONG TERM...VALID FOR THU...FRI...SAT...SUN...MON...
MODELS APPEAR TO BE IN GOOD AGREEMENT WITH ONE ANOTHER THROUGH THE
EXTENDED PERIOD. SOME DISCREPANCIES SHOW UP AROUND 12Z SAT BETWEEN
THEM...THE ECMWF COMES OUT OF LINE WITH ITS PREVIOUS RUN AND HAS
DIFFICULTY HANDLING THE AREA OF LOW PRESSURE AND ASSOCIATED TROUGH
ALONG THE WEST COAST. THE UKMET AND GFSLR KEEP A W/SW FLOW PATTERN
OVER THE REGION WITH THE UKMET HOLDING A RIDGE FURTHER TO THE WEST.
HOWEVER THE ECMWF DOES COME BACK INTO AGREEMENT WITH THE UKMET AND
GFSLR 24HRS LATER. WITH THIS IN MIND AND THE W/SW FLOW HOLDING IN
PLACE THROUGH THE EXTENDED PERIOD...MADE VERY LITTLE CHANGES IN THE
WAY OF TEMPS/WINDS. GFSLR DID INDICATE A WEAK WAVE MOVING INTO THE
REGION THU AFTN AND INCREASED POPS OVER THE SW MTNS TO ACCOUNT FOR
THE FEATURE...OTHERWISE A DRY AND HOT FCST PACKAGE IS IN ORDER.
